Individual harmonics out of required limits

Through a power quality analysis conducted in a photovoltaic power station it was discovered that 5th and 7th individual harmonics of the 35 KV busbar exceeded specified limits.

Individual harmonics out of required limits

Photovoltaic power station operation was the root cause

Through a power quality analysis conducted in a photovoltaic power station it was discovered that 5th and 7th individual harmonics of the 35 KV busbar exceeded specified limits.

An SVG with active harmonic filtering to solve this problem

Considering the harmonic characteristics, engineering cost, construction requirements and the power station configuration, a centralized harmonic control method was recommended. The overall system topology is shown in figure below.
